there is the link.. if you dont have money for the vr4.. you dont have money for this.. and I belive twin large turbos still are better then the big single

Things you will want/need if you plan on useing the big turbo

Large valume fuel pump/2 denso or walboro
fuel pump hot wire kit
injectors
fuel controller
FPR
datologer or somthing to watch knock
wide band 02 sensor..

list goes on.. this is just some of the main things you would need
